In fallout 4, there is a perk called Ghoulish. This allows the player to use radiation to restore hp just like a ghoul. it does nothing to affect the look of the player.

Oh, and by the way, Ghoulish still kills the player if they accumulate too many rads. And I don't see him dying of rads.

EDIT: Okay, this is really bothering me too much. I think I'll just exit stage right and relieve myself from the frustration. Have fun.
